Was it ever used for anything in the late model squares? Or was it always blanked? The reason I ask is I have my cluster all taken apart right now and I noticed there are three holes for the typical light socket used for gauge lighting, turn signals, idiot lights, etc. And my cluster was modded by the PO for a trans temp gauge there, so I can't tell for certain, but it looks like there were dividers there so that hole could have been used for three separate idiot lights. I traced the paths on the printed circuit back to the main connector and two of the three don't even have pins, but one does - looks like it goes to a brown wire. Any thoughts? I will take a pic tomorrow and post if it helps. I should have done it when I was out in the shop tonight.
